To, all w/wmz'tmag concern Be it known that I, HOWARD "W. a citizen of the United States, residing at Baltimore, in the State of 'Maryland, have invented certainnew and useful improve ments in Rail-Holding Devices, of which lng drawing, and will first be described and then pointed out in the claims.

the rail-holdin way crotch in the interior thereof. is a top plan of the head of In the drawing, Figure 1 is a side view of the improved spike device as it would appear when the two parts have been driven into a cross-tie. Fig. 2 is a side View bf the inner prong-part,' as it appears before being driven into the spike-body. Fig. 3 is a vertical section showing both parts of device. Figfi l is a top View of the spi e-body and shows the four- Fig. 5 the inner prong. Fig. 6 is. a back view of the upper portion of both parts of the device. Fig. T is a vertical section of a rail and cross-tie and shows the. spike device in position.

he purpose of a spike device made in two parts, in the fashion here shown, isfirst that the spike-body, A, with its hook-head, Z), that takes onto the base, a, of the rail, D, to hold the rail down, will also have an internal bore; and second, that the inner part, L, that enters said bore will have a prong that shall project from the internal bore, and the said projecting part turn off laterally into the wood of the cross-tie, and therebyaid in preventing the spike-body from loosening.

The spike-body, A, is shown oi cyiindrical shape and a tapered point, ppit has an internal bore, 6, that extends from its top end. down to crotch, f; and four passages or ways, g, lead from this crotch and all four open at the outside of said spikebody. The top of the spihe-body-has a hook head, 5, thatv may have two edges beveled or tapered, as at, it, and a head consists oi three right-angled lower sides, 2', 2 2', and a flat top surface, j, which is above or higher than said three sides; the higher flat surface, j, permits the formation of a rabbet or channel, is, above the three sides. This rabbet or channel, it, serves a useful purthe spike-body is being driven into four crotch, and

will engage the wood of the pose when the prongpart, L, is to be withdrawn, as will be p e'sently described. At the top or the internal bore, 6, said right angled head is provided with a rea1nedout enlargement, m, seen in Figs. 3 and 4; this serves to avoid any partial closure of the top of said internal bore, a, that might otherwise occur by a hammer or sledge striking on the high flat surface, 5', when into the cross-tie.

he inner prong part, L, has a head, a, shaped much the same as the head otthe spike-body, the shank of this prong part has a size that enables it to slip freely down into the internal bore, 6, of said body,

and when this part isfully in-its position the said head, a, will seat upon the high flat surface, 7', as shown in Figs. 1, 3 and 6. It will be seen the rabbet or channel, 70, forms below the head, a, a space into which may be inserted the point of a lever, when the prong part, L, is to be withdrawn.

The. prong part has its lower end divided pointed prongs, 0, which may be of equal length, and the prongs may have any desired shape in ci'osssection.

bend. When the shank part, in; is inserted into the bore, a, the said four prongs will be straight, as in Fig. 1; when the ends of the four prongs reach the crotch, f, each prong will take into one of the four ways of passages, g, that radiate from said upon striking the head, a, with a' hammer the prongs will "bend and the ends of the prongs will project outside of the spike-body, A, as shown in Figs. 1 and 3; and these laterally projecting prongs, 0,

Having thus described my inventio'ir'w'hat I claim and desire to secure by Letters Patent is 1. ilhe improved rail-holding device consisting of a spike body having a central in tern al bore, a hook-head at the top and projecting at one side-said hook-head having three other sides, 2', at right angles to each other, a flat top surface higher than said three sides, and a rabbet orchannel, k, along said three sides and an inner shank fitting within said bore and having a head whose shape is similar to the head of the spike The material. of the prongs will permit them to ll (it:
